8-8 Climate Controls . Air Vents Use the air outlets located in the center and on the side of the instrument panel to direct the airflow. Operation Tips . When you enter a vehicle in cold weather, press the fan up button to the maximum fan level before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of the window. Keep the air path under the front seats clear of objects. This helps air to circulate throughout the vehicle. . Adding outside equipment to the front of the vehicle, such as hood-air deflectors, may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of the vehicle. Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of the windows. .
